AIX 5.3 to 7.1 migration process?

Im having a little trouble deciphering the best approach to perform a SAN booted lpar (clariion) aix migration.

Currently lpar has dedicated HBA's connected to clariion array. With the following ODM/powerpath filesets installed.

EMC.CLARiiON.aix.rte   5.3.0.3  COMMITTED  EMC CLARiiON AIX Support
  EMC.CLARiiON.fcp.rte   5.3.0.3  COMMITTED  EMC CLARiiON FCP Support
  EMCpower.base          5.1.1.0  COMMITTED  PowerPath Base Driver and

  EMCpower.consistency_grp   5.1.1.0  COMMITTED  PowerPath Consistency Group

  EMCpower.migration_enabler

  EMCpower.mpx           5.1.1.0  COMMITTED  PowerPath Multi_Pathing

AIX 7.1 requires ODM v6 but it doesnt look like ODM v6 will run on AIX 5.3. Since powerpath is installed as well, whats the official process for migrating aix?

Do I uninstall powerpath, migrate to aix 7.1 install new ODM and then reinstall new version of powerpath? Any tricks or gotcha's?
